, IMPROVEMENT IN'EXTINGUISHING? FIRES meulLomesgq Specification formingpart of Letters Patent No. [73,987, dated February 22, 1876 applicationfiled i January 20, 1876. i

To all whom it may concern I 'Be it known that I, STEPHEN, S. NEWTON,

, of Binghamton, in the county of Broome and apart of thisspecification.

The invention relates to the combination, with a supply-pipeand nozzle,or a series of supply-pipes and discharging-nozzles, arranged in thevarious rooms of a building, 'of an air-tight tank containing a supplyof water and alkali, a bottle or other vessel containing acid, a valvefor discharging the contents of the bottle into the airtight water-tank,and a device which shall be put into operation automatically by anincrease of temperature of the air in the building, to open the valve ofthe acid bottle orreceiver, whereby carbonic-acid gas is generated inthewater-tank and deliv-.

, cred with the water through the dischargingnozzle. i

Having thus set forth the nature of my invention, I will proceed todescribe different i 1 methods which I have adopted forca-rrying it intopractice.

In Figure 1, A AKA .represent a series of supply-pipes, arranged in orupon the walls of a building, with one or more nozzles or sprinklers, a,in each room, or in as many rooms as may be desired. Underonearrangement each of these nozzle'sisto be provided with one of theusualcheck-valves, held closed "by means of an easily-fusible solder. Asthe construct-ion and operation 0t this class of valves is fullyunderstood,no specific description of them needfbe given; but inpracticeI prefer to use one patented to me in Letters Patent dated December 21,.1875. B is a water-tank, provided with an opening, B, through which tofill it, or it may be filled by means of a force-pump. Inpractice Iprefer-the latter method. 0 is a receiving and supply tank, connectedwith tank B by a pipe,

11, having a cock, b. O is a pipe leading from in fire-extinguishers.

0 D is the acid bottle or receiver,.provided with an opening, d,'intothe tank B. D is a valve-stem, carrying a valve, ti at its lower end,and working in a stnffing-hox, d ,'at the upper part of the bottle oracid receiver. d is an opening into the bottle. E is a lever, fulcrumedat c, and connected to the valvestcm D at c. F is an air-cylinder. F isa piston-rod,-carrying at the lower end a piston, F whichfits air-tightWithin cylinder F. The piston-rod is secured to lever E, at e, by meansof a set-screw,f.' f is a spiral spring surrounding the end ofpiston-rod F, one end of the spring resting against the lever E, theother end pressing against any suitable support. F is an air-pump.

proportion of soda to be varied according to i circumstances, butaboutthat commonly used the pipes A A A the valves of thenozzles beingsecurely closed, until the piston]? and piston rod F are forced upwardand the valve d 'is thrust firmly into the opening d. The

bottle is then filled with acid. As the pistonrod F is forced up thespringf is'compressed. The tension thus produced by thisspring must besuch as to insurethat it will overcome the p friction of the piston inthe cylinder and elsewhere, and the weight. of the acid upon the valve,so that when the air-pressure within the pipeand upon the under side ofthe piston F is released, the spring will force the:

piston down,thus raisingvalve d, and peri .mitting the acid to enter andmix with the al- 11; isevident kaline water in the tank B.

that whenever-the temperature of the room in which oneof the nozzles islocated is raised sufficiently to release easily-fusiblesolder, thisopening of the valve al will takeplace, as will be readily understoodwithout furtherexplanation.

' I do not wish to be limited to the use of the PATENT OFFICE thesupply-pipe to tank 0. (l is a cock in pipe G cis a valve closing theend of pipe I The operation of these devices is as follows: I

Air is then forced into particular acid-bottle hereshown, nor to this Asthe purpose and operation of the receiving-tank (J, pipe 0 and the cockand valve attached thereto are fully set forth in my patent of December21, 1875, it is not necessary to describe them in thispatent.

What I claim is The combination of the following elements, namely aseries of supply-pipes and discharging-nozzles, which are closed by ancasily-fusible solder, a tank containing an alkaline solution, anacid-bottle, an-airpump for compressing air within the supply-pipe, anda piston connected with the acid-bottle and with the supply-pipes,substantially as set forth, whereby, when the air-pressure'within thesupply-pipes is released, the acid will be discharged into the alkalinesolution.

In testimony that I claim the foregoing as my own I atfix my signaturein presence of two witnesses. v
